This is a social science video that answers
- What is earthquake?
- How does earthquake occur?
- What are the different types of waves?
An unexpected movement of the Earth's surface is called an earthquake. When two parts of the earth's surface move suddenly in relation to each other along a fault line, due to tectonic forces, an earthquake occurs. A tremendous amount of energy is released in the form of tremors and vibrations, such earthquakes are called 'Tectonic Earthquakes'. The point of origin of an earthquake is called the 'focus', while the point directly above it, on the surface of the earth is called the 'epicentre'. Owing to the strong vibrations around the point of origin, the degree of destruction is greater around the epicentre. The branch of knowledge that deals with the study of earthquakes is called Seismology, and the experts who study seismic waves are called Seismologists.
There are three types of Seismic waves that spread in all directions from the focus. They are the P. S, and L waves. The compressional waves are the first to reach the earthquake recording station as they travel 1.7 times faster than the shear waves and are therefore called 'P' (Primary) waves, while the shear waves are called 'S' (Secondary) waves.
The primary waves cause the particles of rock to vibrate forwards and backwards in the direction of the waves. Secondary waves, on the other hand cause the particles to oscillate at right angles to the direction of the waves. When P and S reach the surface of the earth, they get converted into 'L' long waves that travel along the surface, vibrating horizontally at right angles to the direction of the waves called 'Love waves' or Rayleigh waves as they also travel like sea waves. The most violent shocks and subsequent destruction is caused by the L waves.
While the S waves cannot pass through liquids, the P waves can pass through any medium. This helped seismologists to learn more about the interiors of the earth.
The instrument used to detect and record seismic waves is called a Seismograph. The recorded material appears like a graph and is called a Seismogram.
Based on the depth of their foci, earthquakes are classified into tree types. They are:
(a) Deep-focus earthquakes that occur at depths exceeding 300 Kms, the reasons for which have not yet been identified.
(b) Intermediate focus earthquakes with depths of foci ranging between 55 and 300 Kms.
(c) Shallow-focus earthquakes with depths lesser than 55 Kms.
The area on the surface of the earth increases along with the increase in depth of the focus, while the intensity increases with the decrease in depth of the focus.
To measure the magnitude of the earthquakes, aRichter Scale is used. The point-scale is arranged in such a way that each of the units on the scale is equivalent to 30 times the energy released by the previous unit. While a magnitude of 2 is seldom felt, a magnitude of 7 indicates the lower limit of an earthquake that has a devastating effect over a large area.

In this project we will learn how to design Arduino EarthquakeDetectorAlarm with SeismicGraph. We have used ADXL335 3 axis Accelerometer as a sensor for detecting tilting, trembling or any shaking movement of earthquake. We have interfaced ADXL335 Accelerometer with Arduino and LCD display for designing Arduino Earthquake Detector Alarm with Seismic Graph.
The Arduino code as well as procesing IDE code both are given below. The processing IDE code helps in drawing the graph of the tilting state. The buzzer or LED is used as an alarm whenever the shaking threshold goes higher.

Facebook Graph Search

Facebook Graph Search was a semantic search engine that was introduced by Facebook in March 2013. It was designed to give answers to user natural language queries rather than a list of links. The Graph Search feature combined the big data acquired from its over one billion users and external data into a search engine providing user-specific search results. In a presentation headed by Facebook CEO Mark Zuckerberg, it was announced that the Graph Search algorithm finds information from within a user's network of friends. Additional results were provided by Microsoft's Bing search engine. In July it was made available to all users using the U.S. English version of Facebook. In December 2014, Facebook changed its search features, dropping partnership with Bing, and eliminating most of the search patterns.

Development

The Graph Search Features was launched in Beta January 2013 as a limited preview for some English users in the United States. Company reports indicate that the service launched to between tens and hundreds of thousands of users. As of August 2013, Graph Search is available to all English users in the US.

Singles

The album's lead single, "Bring It Back" was released on April 10, 2004. The song serves its production and as a featured guest vocals from then-Cash Money producer Mannie Fresh.

The album's second single, "Go D.J." was released on October 5, 2004. Mannie Fresh's production were featured on the song; the same producer, who recently produced the song "Bring It Back", in which latter released as his first single.

The album's third single "Earthquake" was released on November 16, 2004. The production on the song and as a featured guest vocals was from Jazze Pha.

Commercial performance

2011 Tōhoku earthquake and tsunami

The 2011 earthquake off the Pacific coast of Tōhoku(東北地方太平洋沖地震,Tōhoku-chihō Taiheiyō Oki Jishin) was a magnitude 9.0 (Mw) underseamegathrust earthquake off the coast of Japan that occurred at 14:46 JST (05:46 UTC) on Friday 11 March 2011, with the epicentre approximately 70 kilometres (43mi) east of the Oshika Peninsula of Tōhoku and the hypocenter at an underwater depth of approximately 30km (19mi). The earthquake is also often referred to in Japan as the Great East Japan earthquake(東日本大震災,Higashi nihon daishinsai) and also known as the 2011 Tohoku earthquake, and the 3.11 earthquake. It was the most powerful earthquake ever recorded to have hit Japan, and the fourth most powerful earthquake in the world since modern record-keeping began in 1900. The earthquake triggered powerful tsunami waves that reached heights of up to 40.5 metres (133ft) in Miyako in Tōhoku's Iwate Prefecture, and which, in the Sendai area, travelled up to 10km (6mi) inland. The earthquake moved Honshu (the main island of Japan) 2.4m (8ft) east, shifted the Earth on its axis by estimates of between 10cm (4in) and 25cm (10in), and generated sound waves detected by the low-orbiting GOCE satellite.

Richter magnitude scale

The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the energy released by an earthquake. The Richter scale, developed in the 1930s, is a base-10logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.

As measured with a seismometer, an earthquake that registers 5.0 on the Richter scale has a shaking amplitude 10 times that of an earthquake that registered 4.0, and thus corresponds to a release of energy 31.6 times that released by the lesser earthquake. The Richter scale was succeeded in the 1970s by the moment magnitude scale. This is now the scale used by the United States Geological Survey to estimate magnitudes for all modern large earthquakes.

Development

In 1935, the seismologistsCharles Francis Richter and Beno Gutenberg, of the California Institute of Technology, developed the (future) Richter magnitude scale, specifically for measuring earthquakes in a given area of study in California, as recorded and measured with the Wood-Anderson torsion seismograph. Originally, Richter reported mathematical values to the nearest quarter of a unit, but the values later were reported with one decimal place; the local magnitude scale compared the magnitudes of different earthquakes. Richter derived his earthquake-magnitude scale from the apparent magnitude scale used to measure the brightness of stars.

A travel-time curve is a graph of the time that it takes for seismic waves to travel from the epicenter of an earthquake seismograph stations varying distances away. The velocity of seismic waves through different materials yield information about Earth?s deep interior. IRIS? travel times graphic for the 1994Northridge, CA earthquake (described in IRIS poster, No.5. Exploring the Earth Using Seismology, http://www.iris.edu/hq/inclass/poster/3) is animated to show how travel times are determined. Seismic waves bounce the buildings to merely to illustrate arrival times and wave behavior, not to depict reality. The resultant seismograms show that stations around the world record somewhat predictable arrival times.

In this project we will learn how to design Arduino EarthquakeDetectorAlarm with SeismicGraph. We have used ADXL335 3 axis Accelerometer as a sensor for detecting tilting, trembling or any shaking movement of earthquake. We have interfaced ADXL335 Accelerometer with Arduino and LCD display for designing Arduino Earthquake Detector Alarm with Seismic Graph.
The Arduino code as well as procesing IDE code both are given below. The processing IDE code helps in drawing the graph of the tilting state. The buzzer or LED is used as an alarm whenever the shaking threshold goes higher.

A travel-time curve is a graph of the time that it takes for seismic waves to travel from the epicenter of an earthquake seismograph stations varying distances away. The velocity of seismic waves through different materials yield information about Earth?s deep interior. IRIS? travel times graphic for the 1994Northridge, CA earthquake (described in IRIS poster, No.5. Exploring the Earth Using Seismology, http://www.iris.edu/hq/inclass/poster/3) is animated to show how travel times are determined. Seismic waves bounce the buildings to merely to illustrate arrival times and wave behavior, not to depict reality. The resultant seismograms show that stations around the world record somewhat predictable arrival times.

How does Earthquake occur with explanation - Social Science 3D animation video in HD

This is a social science video that answers
- What is earthquake?
- How does earthquake occur?
- What are the different types of waves?
An unexpected movement of the Earth's surface is called an earthquake. When two parts of the earth's surface move suddenly in relation to each other along a fault line, due to tectonic forces, an earthquake occurs. A tremendous amount of energy is released in the form of tremors and vibrations, such earthquakes are called 'Tectonic Earthquakes'. The point of origin of an earthquake is called the 'focus', while the point directly above it, on the surface of the earth is called the 'epicentre'. Owing to the strong vibrations around the point of origin, the degree of destruction is greater around the epicentre. The branch of knowledge that deals with the study of earthquakes is called Seismology, and the experts who study seismic waves are called Seismologists.
There are three types of Seismic waves that spread in all directions from the focus. They are the P. S, and L waves. The compressional waves are the first to reach the earthquake recording station as they travel 1.7 times faster than the shear waves and are therefore called 'P' (Primary) waves, while the shear waves are called 'S' (Secondary) waves.
The primary waves cause the particles of rock to vibrate forwards and backwards in the direction of the waves. Secondary waves, on the other hand cause the particles to oscillate at right angles to the direction of the waves. When P and S reach the surface of the earth, they get converted into 'L' long waves that travel along the surface, vibrating horizontally at right angles to the direction of the waves called 'Love waves' or Rayleigh waves as they also travel like sea waves. The most violent shocks and subsequent destruction is caused by the L waves.
While the S waves cannot pass through liquids, the P waves can pass through any medium. This helped seismologists to learn more about the interiors of the earth.
The instrument used to detect and record seismic waves is called a Seismograph. The recorded material appears like a graph and is called a Seismogram.
Based on the depth of their foci, earthquakes are classified into tree types. They are:
(a) Deep-focus earthquakes that occur at depths exceeding 300 Kms, the reasons for which have not yet been identified.
(b) Intermediate focus earthquakes with depths of foci ranging between 55 and 300 Kms.
(c) Shallow-focus earthquakes with depths lesser than 55 Kms.
The area on the surface of the earth increases along with the increase in depth of the focus, while the intensity increases with the decrease in depth of the focus.
To measure the magnitude of the earthquakes, aRichter Scale is used. The point-scale is arranged in such a way that each of the units on the scale is equivalent to 30 times the energy released by the previous unit. While a magnitude of 2 is seldom felt, a magnitude of 7 indicates the lower limit of an earthquake that has a devastating effect over a large area.

In this project we will learn how to design Arduino EarthquakeDetectorAlarm with SeismicGraph. We have used ADXL335 3 axis Accelerometer as a sensor for detecting tilting, trembling or any shaking movement of earthquake. We have interfaced ADXL335 Accelerometer with Arduino and LCD display for designing Arduino Earthquake Detector Alarm with Seismic Graph.
The Arduino code as well as procesing IDE code both are given below. The processing IDE code helps in drawing the graph of the tilting state. The buzzer or LED is used as an alarm whenever the shaking threshold goes higher.
